Abstract

The present invention relates to a refrigerator bottom plate fixing device, and in particular, a part of a bottom plate forming a top surface of a machine room in which a compressor is mounted is cut to form a fastener, and the bottom plate is inserted into a fixing hole formed at a reinforcement angle and bent. Was fixed to the refrigerator body. In other words, one side of the fixing part of the bottom plate seated on the reinforcement angle was cut to a predetermined size to form a fastener, and a tab hole was formed on the other side, and the fixing hole and the tab hole corresponding to the fastener and the tap hole of the bottom plate were also formed. Therefore, when the fixture is bent while the fixture of the bottom plate is inserted into the fixing hole of the reinforcement angle, the bottom plate can be fixed to the refrigerator main body, thereby reducing the number of fixing screws for fixing the bottom plate to the refrigerator main body. Accordingly, the cost of the product can be reduced, and the productivity of the work can be expected due to the reduction of the number of parts.

Description

An apparatus for fixing the lower panel of a refrigerator

The present invention relates to a refrigerator bottom plate fixing device, and more particularly, to a refrigerator bottom plate fixing device which can easily combine a bottom plate forming an upper surface of a machine room with a refrigerator main body, and also improve the productivity of a product by reducing the number of parts.

In general, a refrigerator is a device for preserving the freshness of food by maintaining the temperature in the refrigerator at a low temperature using the latent heat of evaporation of the refrigerant gas according to the refrigeration cycle of the compressor, the condenser, the expansion valve and the evaporator.

That is, when the compressor compresses the refrigerant gas and raises the pressure and temperature of the refrigerant gas to the saturation pressure, the condenser absorbs the heat of the refrigerant gas of high temperature and high pressure by using water or air to condense and liquefy the refrigerant gas. .

The refrigerant gas condensed and liquefied is lowered in temperature and pressure by the throttling action of the expansion valve, and the refrigerant gas is evaporated in the evaporator to absorb heat from the stored food and perform the freezing action.

3 is a partial side cross-sectional view showing a general refrigerator, in which a compressor 150 for compressing the refrigerant gas to increase the pressure and temperature of the refrigerant gas to a saturation pressure is mounted in the machine room 160 formed under the refrigerator main body 100. It is.

The machine room 160 is formed by the bottom plate 120 and the reinforcement angle 140, and the heat generated from the machine room 160 is not between the inner plate 110 and the bottom plate 120 so as not to be transferred to the cavity for storing food. The urethane member 130 which is a heat insulating material is foamed, and it is sealed by the cover 161 so that the machine room 160 may not be exposed to the outside.

4 is an exploded perspective view illustrating a coupling state of the bottom plate and the refrigerator body illustrated in FIG. 3, and FIG. 5 is a cross-sectional view of main parts of the bottom plate illustrated in FIG. 4, coupled to the refrigerator body.

As shown in the figure, in the reinforcement angle 140 mounted inside the side panel 170, the tab hole 141 for the fixing screw 180 for fixing the bottom plate 120 to the refrigerator main body 100 and the front and Tab holes 122 corresponding to the tab holes 141 formed in the reinforcement angle 140 are also formed in the fixing part 121 of the bottom plate 120 which is formed at the rear, respectively, and is seated on the reinforcement angle 140.

Therefore, the bottom plate 120 is pushed into the lower portion of the refrigerator main body 100 to seat the fixing part 121 of the bottom plate 120 on the reinforcement angle 140, and then the tab hole 122 and the reinforcement angle of the bottom plate 120 are fixed. When the fixing screw 180 is fastened in a state where the tap holes 141 of the 140 are matched with each other, the bottom plate 120 may be fixed to the refrigerator main body 100.

However, when the bottom plate is coupled to the reinforcement angle by using the fixing screw as described above, the number of parts increases as a plurality of fixing screws are required, and thus there is a problem that productivity may decrease due to the increase in the number of working processes. .

The present invention is designed to solve the above problems, it is possible to easily combine the bottom plate forming the upper surface of the machine room in which the compressor is seated to the refrigerator body, and also to reduce the number of parts, the bottom plate of the refrigerator to improve productivity It is an object to provide a fixing device.

In order to achieve the above object, the present invention, in a conventional refrigerator, is formed on the reinforcement angle by cutting one side of the fixing part of the bottom plate to form a top surface of the machine room to a predetermined size to form a fastener and the other side to form a tab hole In the reinforcement angle, the fixing hole and the tab hole corresponding to the fixture and the tab hole of the bottom plate are formed, but the fixture is bent in the state inserted into the fixing hole is characterized in that it is fixed to the reinforcement angle.

Hereinafter, with reference to the accompanying drawings a preferred embodiment of the present invention will be described in detail.

1 is an exploded perspective view illustrating a coupling state of a bottom plate and a refrigerator body having a fixing device according to the present invention, and FIG. 2 is a cross-sectional view of main parts of the bottom plate illustrated in FIG. 1 coupled to the refrigerator body.

As shown in the figure, a fastener 43 in which the fixing portion 41 is cut to a predetermined size is formed in the front portion of the fixing portion 41 of the bottom plate 40 forming the upper surface of the machine room in which the compressor is seated. In the rear portion, a tab hole 42 for a fixing screw is formed.

On the other hand, the fixing hole 21 and the tap hole 22 corresponding to the fastener 43 and the tap hole 42 are also formed in the reinforcing angle 20 on which the fixing part 41 of the bottom plate 40 is seated, respectively.

Therefore, the bottom plate 40 is pushed into the lower part of the refrigerator main body 10 so that the fastener 43 of the fixing part 41 is inserted into the fixing hole 21 of the reinforcing angle 20. 41) is seated on the reinforcement angle (20).

When the bottom plate 40 is bent on the fixing hole 43 inserted into the fixing hole 21 in the state in which the bottom plate 40 is seated on the reinforcing angle 20, one side of the fixing part 41 of the bottom plate 40 is reinforced. The bottom plate 40 can be fixed to the refrigerator main body 10 when the tab hole 42 formed at the other side of the fixing part 41 is aligned with the tab hole 22 of the reinforcing angle 20 and fastened with a fixing screw. Can be.

As described above, the present invention cuts a part of the fixing part of the bottom plate to form a fastener, and the fastener is inserted into the fixing hole formed in the reinforcing angle and bent to fix the bottom plate to the refrigerator main body. Therefore, since the number of fixing screws for fixing the bottom plate to the refrigerator main body can be reduced, the cost of the product can be reduced, and the reduction in the number of parts due to the reduction of the number of parts can be expected, thereby improving productivity.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible. Therefore, the true technical protection scope of the present invention should be defined only by the scope of the attached utility model registration request.
